Center of Gravity
Today we took the outline of shapes from the game "Blockhead" to find the Center of Gravity of each shape. To do this, we
took a test tube plug that was on a string (string A) and hung it from a metal rod. Then we took the outline of the shape and punched 3 small holes in it, then hung it from a string as well (string B). When the objects stopped moving, we traced where string A crossed across the outline. Next, we took the string and strung it through one of the other holes. We repeated the process of tracing where string a crossed over the shape. Once more, we strung the string through the last hole and traced were string A crossed over the shape.

Today we selected three sports and used the concept of Ionic Bonds, Covalent Bonds, and Metallic Bonds to describe how these sports are like each bond. Here are our three sports:
Soccer: Soccer is like a Metallic Bond. The soccer players are like the electrons in the metal and the ball is like the positively charged ions. All of the players on the field/electrons are attracted to the ball/protons.
Field Hockey: Field Hockey is like an Ionic Bond. The stick is the positive ion and the ball is the negative ion. When you are dribbling down the field, the ball is attracted to the stick because you are keeping it close to you-this way you never lose control.
Volleyball: Volleyball is like a Covalent Bond. The two teams are like the nuclei and the ball is like the electron going back and forth-being shared.

A Metallic Bond has electrons that "swim" freely throughout the object.
Characteristics of Metallic Bonds are:
~electrical conductivity
~can be reshaped
~can bend without breaking
~has an attraction of positive ions and free moving electrons
An Ionic Bond is the force of attraction between oppositely charged ions.
Characteristics of Ionic Bonds:
~compounds have crystal-lattice structure
~transfer of electrons
~a metal reacts with a nonmetal
A Covelant Bond is the force of attraction between the nuclei of atoms and the electrons shared by the atoms.
Characteristics of Covelant Bonds:
~attraction between nuclei and shared electrons
~two or more nonmetals are involved

We did a lab on 3 substances:
Bromothymol Blue, Sodium Bicarbonate, and Calcium Chloride.
Just some extra information on Sodium Bicarbonate!!!
symbol-NaHCO3
Here is a very good link to explain what sodium bicarbonate is!!! Sodium Bicarbonate is the key ingredient in baking soda. WOW!!!!!
